  • Lighting device for display of graphic characters
    Patent number: 6079839
    Abstract: A lighting device includes a body and one or more light sources that introduce light into the body. The one or more light sources include at least one strip-like source which continuously emits light with respect to its longitudinal direction. The body light has a light exit face on one side and by which light introduced into the body passes out of the body. The strip-like source is directly fitted on or in the body in such a way that the light which passes out of a side of the strip-like light source facing the body substantially completely enters the body. The body has a lateral face at least partly constructed as a mirror or reflector for light traveling in the body and at least partly to the light exit face.
